Speccaton of Letters Patent.

Patented Apr. 23, 1912.

Application filed June 27, 1910. Serial No. 569,229.

To all whom it may concern:

Be it known that I, JOHN W. DowDEN, a citizen of the United States,residing at Reeves, in the parish of Calcasieu and State of Louisiana,have invented a certain new and useful Improvement in Firearms, of whichthe following is a specification.

My invention relates to a new and useful improvement in firearms, andhas for its `object to provide a lock upon the loading yfrod to preventthe same from being operated until unlocked by the user.

Another object of the invention is to provide means for regulating thepressure of the spring which returns the breech block to its normalposition.l

Another object of the invention is to provide a take-down spring, theend of which is bent inthe shape of a hawks bill, thereby preventing itsend from coming in contact with the other parts of the fire arm, whichwould otherwise mar and break portions thereof. j

Another object of the invention is to form the cartridge stop in theshape of a hawk bill so that the breech block may readily slide over thesame vwithout injuring it, the ends of said cartridge stop projectinginto the magazine, thereby holding the outermost cartridge in placeuntil the one in the barrel has been ejected.

Another object of the invention is to mount a spring upon the upperportion of the breech block, said spring carrying a roller adapted tooperate against the upper portion of the receiver said spring and rollerforcing the breech block downward so that it will be held in constantContact with the cartridge stop, at the same time preventing rattlingVdue to the loose fit of the breech block within the receiver. f

Astill further object of the invention is to provide a hammer having twonotches for i 'li-dengagement with the trigger, the uppermost notchengaging the trigger, if said trigger is held back, which will preventthe discharge of the firearm, the lower notch engaging the trigger aftersaid trigger is released and from which position the firearm isdischarged.

With these ends in view, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I will describeits construction in detail, referring by letter to the accompanyingdrawing forming a part of this specification, in which- Figure l is abroken side elevation of a firearm made in accordance with myimprovement, portions thereof being shown in section to more fullyillustrate the construction. Fig. 2, an end view of the crown. Fig. 3, aside elevation of a portion thereof parts being broken away to show itsconstruct-ion. Fig. 4, a rear or end view of the hammer. Fig. 5, a sideelevation thereof. Fig. 6, a side elevation of the rod about which iscoiled the spring for operating the crown. Fig. 7, an end view of thecircular nut which is threaded on the rod shown in Fig. 6. Fig. 8, aside elevation thereof. Fig. 9, an end view of the loading rod. Fig. 10,a side elevation thereof showing a portion in section, and Fig. l1 aside elevation of the metal portion of the stock in which is pivoted thehammer, the end of the magazine being shown in section. Fig. 12, alongitudinal vertical section through the receiver and rear stockshowing the hammer and trigger in their cooperative relations.

In carrying out my invention as here embodied, A represents the woodenstock and B the separable portion of the frame mounted upon the end ofthe wooden stock in any suitable manner. In the metal portion of thestock is mounted the take down spring C, the end of which is bent atright angles to form the hawk bill D, and this spring is adapted toengage the lower portion E of the front of the receiver F. This springis preferably made in the shape of a hawks bill in order to prevent theend thereof catching in the edge of the receiver when the gun is beingassembled.

G is the magazine which is mounted in the stock, the end thereofextending into the per portion of the cartridge stop J when said hammeris in its forward position, thus pressing the cartridge stop downwardagainst the action of the spring L and causing its point O to engage theoutermost cartridge in the magazine. By bending the end of the cartridgestop in this position it produces what is known as a hawk bill so thatthe same will engage the cartridge and at the same time eliminate thesharp ends or corners which might otherwise come in contact with thebreech block and injure the parts thereof.

The hammer is provided with two notches P and Q, each of which isadapted to engage the trigger shown at R, the notch P being of greaterdepth in relation to the pivot point of the hammer so that if thetrigger is held back, when the fire arm is re-loaded said trigger willengage the notch P and hold the hammer in its cocked position, but assoon as the trigger is released the hammer will move forward slightlyuntil said trigger engages the notch Q, still holding the hammer cocked,from which position the firearm may be discharged when the trigger ispulled. From this description it will be seen that should the user ofthe firearm hold the trigger back and endeavor to reload it, the firearmwill not be discharged until the trigger is released and then pulled.

R denotes the breech block, having an arm S which rests beneath thebarrel T and is caused to reciprocate by the loading rod U. In the topof the breech block is formed the groove V, in `which is mounted thespring W, on the rear end of which is journaled the roller X, saidroller operating against the inner face of the top of the receiver F, asplainly shown in Fig. 1, the action of the spring holding the breechblock downward or in close proximity to the cartridge stop J.

The arm S is beifurcated so that it straddles t-he lug Y carried by thereceiver and in this lug is threaded the rod Z, the end of which extendsthrough the outer end or bridge A of the arm S. About this rod is coiledthe spring B, one end resting against the bridge of the arm, theopposite end against the circular nut C which is threaded upon the rodZ. This nut is provided wit-h a number of wrench holes D whereby thesame may be threaded along the rod for regulating the pressure of thespring B.

The loading rod U is provided with two chambers D2 and E leading fromthe opposite ends thereof, the chamber D2 having a coiled spring Fmounted therein, one end of which rests against the top of said chamber,the other end against the rod Z. In the chamber E', is also mounted acoil spring H', one end of which rests against the inner end of saidchamber, the opposite end carrying a plunger I which engages the nose Jof the knife edge lock K, which is pivoted to the cap L at M, said capbeing mounted upon the end of the loading rod U.

Over the rod Z the arm S of the breech block and the loading rod isplaced, the fore stock N. Over the end of the fore stock N is placed thetip O against which rests the outer end of the lock K when the same isparallel with the loading rod, which will preventany movement of saidloading rod until said lock is drawn downward by the user of the firearm.

In practice the metal portion ofthe stock is inserted in the receiver,the take down spring C engaging the under side E of the receiver whichwill force the metal portion B of the stock upward, at all times takingup any slack between the parts, the carfg tridge being in the magazine.To load the' gun, the lock K is drawn downward, then by pushingrearwardly on the loading rod U, the inner end of which rests againstthe bridge of the breech block arm, said breech block will be forcedrearwardly against the action of the spring B, the tension of which hasbeen regulated by the nut C mounted upon the rod.Z. The spring W on topof the breech block will normally hold said breech block depressed, theroller X on the end of said spring allowing the same to move with littlefriction, and as the breech block is moved rearwardly the hammer M willbe cocked, removing the pressure from the cartridge stop J, so that thepoint O disengages the cartridge. in the magazine, allowing it to moveforward to the barrel. When the loading rod is released the spring Bwill draw the breech block to its normal position, the spring Fassisting in relieving the pressure of the loading rod upon the arm S.If in this operation the trigger has been held back it will engage thenotch P of the hammer so that said hammer cannot fall to discharge thelire arm, and as soon as the trigger is released it will engage thenotch Q, at which tim-e the fire arm may be discharged in theordinary'manner.

Of course I do not wish to be limited to the exact details ofconstruction here shown, as these may be varied within the limits of theappended claims without departing i from the spirit of my invention.

Having thus fully described my invention, what I claim as new anduseful, is-
